Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat and fixed curved display apparatuses have limited viewing angles and cannot adjust their curvature to suit user location or image content, limiting the ability to provide three-dimensional or immersive images.
Innovation Solution
A display apparatus with a flexible display panel, a central support assembly, and edge support assemblies that allow the curvature and height of the display panel to be adjusted using a simple structure, including a linear driver to move the central support assembly and rotate the edge support assemblies, reducing tensile stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed curved display panel is used, then the viewing angle is improved, but the adaptability to different user locations and image content is worsened
Solution Approach 1:
The display panel transitions from a fixed curved state to a dynamically adjustable curved state. The patent implements a curvature adjustment mechanism that allows the display panel to change its curvature radius according to different usage scenarios, user positions, and image content types, thereby simultaneously achieving good viewing angles and high adaptability.
2Adaptability or versatility
If a flexible display panel with adjustable curvature is used, then the adaptability is improved, but the device complexity is worsened
Solution Approach 1:
The support assembly is divided into multiple independent components including a first support assembly and a second support assembly that can move relative to each other. This segmentation allows the curvature adjustment function to be achieved through simple relative movements of modular components, reducing overall structural complexity while maintaining adaptability.
Solution Approach 2:
The support assembly is designed to perform multiple functions: it provides structural support for the display panel, enables curvature adjustment, and allows height adjustment. By integrating these functions into a single multi-functional assembly, the patent avoids the need for separate mechanisms for each function, thereby reducing device complexity.
3Device complexity
If the central support assembly structure is simplified, then the device complexity is reduced, but the reliability of the display panel is worsened due to increased tensile stress
Solution Approach 1:
The patent adjusts the curvature radius parameter dynamically to optimize stress distribution. By changing the curvature radius according to different display content and viewing conditions, the system can reduce tensile stress on the display panel while maintaining the simplified support structure, thereby preserving reliability.
